WlRE-BARBlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 295,208, dated March18, 1884:. Application filed November 12, 1883. (No model.)

To all whom it may concern.-

.Be it known that I, DANIEL G. STOVER, a resident of Freeport, in thecounty of Stephenson and State of Illinois, have invented certain newand useful Improvements in Fire- Barbing Machines; and I do herebydeclare the ibllowing to be a full, clear, and exact de scription of theinvention, such aswill enable others skilled in the art to which itpertains to make and use the same.

My invention is an improved machine for applying barbs to a single wire,the wire so barbed being adapted for use as a single-strand fencingmaterial, or for intertwisting with a 1 second wire, either plain orbarbed, to form a two-strand cable.

The machine is fully described, explained, and claimed in the followingspecification, and shown in the accompanying drawings, in

which- Figure 1 is a plan of the entire machine; Fig. 2, a sideelevation thereof, looking in the direction indicated by the arrow a,Fig. 1, the bed of the machine being cut away by a vertical planepassing through thelinewy, Fig. 1; Fig. 3, an end view of the machine,looking in the direction indicated by the arrow c, Fig. 1; Fig. 4, anenlarged elevation of the barbforming sleeve M; Fig. 5, abottom view of0 same; 6, a vertical section, andllig. 7 a plan, of the inner end ofthe lever D, the

plane of section in Fig. 6 passing through the,

line at n, Fig. 7; Fig. 8, a front elevation of the sleeve M, showingthe lnainwire and barbwire in position after the latter has been bentinto a staple; Fig. 9, a side elevation of the barb-wire bent into astaple, the positions of the sleeve M and lever D being shown in dottedlines; Figs. 10, 11, and 13, views of the completed barb; and Figs. 12,1 1, and 15, views showing the forms of the cams G O G.

In all the general views of the'machine, except Fig. 1, the devices forfeeding and severing the barb-wire are omitted.

In these views, A is the bed of the'machine; B, themain shaft thereof,and B a side shaft connected with the main shaft by miter-gears.

Near the middle of the bed is avertical column, H, formed integrallywith a base, G, and

mot-ion from the cams G 0, respectively, both with avertical cylindricalbearing, H, theba-se G being rigidly fastened to the bed.

In the bearing H is journaled a sleeve, M, onwhichisrigidlymounted,immediatelyabove the bearing H, a pinion, K,andwithin the sleevemovesverticallyapunclnO. TheheadJ of thepunch O ispivoted in the bifurcated end I of a bent lever, D, which oscillatesvertically about a horizontal pivot, E, passing through the lever andthrough two ears, H, at the summit of the column II. The rear end of thelever D rests on a cam, 0", mounted on the shaft B, the contact of thelever and cam being preserved by a spring, S, one end of which isattached to the lever, while the other end is fastenedto the column H.The rotation of the shaft B and cam G alternately raiscsand lowers theend of the lever D, and thus imparts reciprocal vertical motion to thepunch O. A spring, S, attached to the column H, rests on the pinion K,and prevents any vertical motion or jar of the sleeve M. The pinion Kengages with a horizontally-oscillating geared segment, L, which isformed integrally with a lever, D. The lever is pivoted near its middleon a vertical post, E, which is rigidly fastened to the bed of themachine, and the outer free end of the lever carries an anti'frictionroller, .N, which rests against the edge of a cam, G, rigidly mounted onthe shaft .13. The contact of the roller and cam is maintained by aspring, S, one end of which is fastened to the free end of the leverD"and the other end to a stationary post, F, and the rotation of the camG imparts reciprocal horizontal motion to the lever D, and segment Landreciprocal rotary motion to the sleeve M.

In front of the supporting-column H, heretofore referred to, are twohorizontal levers, D D, very nearly at right angles to the shaft 90 Boththese levers are pivoted on a horizontal shaft, E, supported by suitablestationary bearin gs attached to the bed A. The outer ends of theselevers receive reciprocal vertical of said cams being rigidly mounted onthe shaft 13. The lever D is held in contact with the periphery of thecam by a spring, S,

from the face P of the lever D.

fastened to the lever and to the bed of the machine, while the lever Dis provided with a pin projecting from its side face and entering agroove in theside face ofthe cam O. The forms of the cams O O O arefully shown in Figs. 12, 14, and 15, respectively. The lever D extendsfrom the cam O at one side of the machine to a point slightly beyond thecolumn H, and is provided at its inner end with a horizontal spindle, e,projecting from its front face, both lever and spindle being drilled ina line coincident with the axis of the spindle for the passage andsupport of the main wire to be barbed. The lever D is of practically thesame length as the lever D, and is provided near its inner end with araised face, P, forming part of the upper surface of the lever, and soplaced as to lie directly under the sleeve M and punch O. The face P iscut by a diametrical groove, p, parallel with the shaft B, and in theline of the main wire 20, and in this groove the main wire rests duringthe operation of intertwisting the ends of the barb, as hereinafter setforth. A a

At right angles to the groove p is a vertical recess, 9, of such formand dimensions as to receive the middle of a barb when bent about themain wire in the form of a staple. (See Figs. 6, 7, and 9.)

The periphery of the sleeve M is cut by two vertical tapering notches, QQ.widest and deepest at the base or bottom of the sleeve, and taperinggradually upward, as shown in Figs. 4 and 5. Each of the notches has twolips, R

5 R, the lip B being short, nearly radiahand preferably somewhatconcave, while the lip R is longer and slightly convex, and forms a camabout which the end of the barb may slip without obstruction. The lowerface of the 0 spindle M is provided with two wrappinglugs 5 that therotation of the shafts B B and the cams mounted thereon impartsreciprocal rotary motion to the sleeve M, reciprocal vertical motion tothe punch O, and reciprocal vertical motion to the levers D D, and thatthese motions are independent of each other. It is further evident thatthe various cams may be so timed as to produce these motions of thedifferent parts in any desired order and at any desired intervals withinthe limits of the time required for a revolution of the main shaft. Themanner in which these movements of the parts co-operate in the formationof a barb is as follows: The main wire 10 being in the position shown inFigs. 1 and 2, the punch O and 60 the inner end of the lever D, with itswire-sup portingspindle e, are raised to their highest positions,respectively, while the inner end of the lever D is dropped to itslowest position. the main wire being thus freed wholly While the mainwire is in this position the-barb-wire w the face P is raised until itstrikes the pins i i of the sleeve M, and the supporting-spindle e islowered until it isin line with the groove p; and at the same time thepunch O descends upon the main wire and forces it into the groove. Atthe instant when the punch 0 reaches the main wire, the barbis severedby suitable knivesv situated between the main wire and the barb-feedingmechanism. The main wire rests on the center of the severed barb, whichlies over the recess p, and the downward pressure of the punch O on themain wire bends the middle of the barb downward into the recess, Whileits ends move upward, the barb taking the form of. a staple whose legsare nearly at right angles to each other, and forty-five degrees above ahorizontal line, and the legs when at theirhighest position beingreceived by the notches in the sleeve M. (See Figs. 8 and 9.) The sleeveM is now revolved in the direction indicated by the arrow in Fig. 5, andby the arrow at in Fig.1, the short concave lips R of the notches Q Qpressing laterally against thelegs of the staple and tending to rotatethem about their common center and intertwist them. As

rotation of the sleeve continues" until it has,

completed an entire revolution of three hundred and sixty degrees, whenthe barb has the form shown in Figs. 10, 11, and 13, the intertwist-edlegs lying wholly in the same plane and forming a flat central rosette,from which the points project in tangentlincs. The punch O, which at thebeginning of the rotation of the sleeve M rests on the main wire, israised as soon as the sleeve brings the legs of the staple sufficientlyacross the main wire to hold the latter in place. This is necessary, inorder that the legs, when intertwisted, may lie in close contact. \Verethe punchto rest on the main wire during the entire rotation of thesleeve M, the rosette formed by the intertwisted legs of the barb wouldhave acentral opening of a diameter equal to that of the lower end ofthe punch. The barb being brought to the completed form shown in Figs.10, 11, and 13, the supporting-spindle e is raised and the face P isdropped until the barb and main Wire are wholly free from the face. Themain wire is then-fed forward in the direction indicated by the arrow a,Fig.

1, when themachine is ready for thefeeding and forming of another barb,the feed of the main wire being, of course, through a space equal to thedesired distance between two contiguous barbs on the main wire.

The punch O, instead of being separate from the sleeve M, may be formedintegrally with it, and project below its lower face a distance aboutequal to the diameter of the barbwire. Inthis case, however, the entiresleeve and punch must have vertical as well as rotary motion, and thewrapping-pins i must mpve longitudinally in sockets in order to vary thedistance they project below the face of the sleeve. preferable to makethe punch. independent of the sleeve, as shown.

In the drawings no devices for feeding forward the main wire are shown,as any intermittent feed may be used.

The devices shown in Fig. 1 for feeding and cutting the barb-wire aresubstantially the same as are shown in my Patent No. 278,624, issued May29, 1888; but any other equivalent devices may take the place of thesewithout in any way afi'ectiug my invention.
